WEBVTT Kind: captions; Language: en 00:00:03.000 --> 00:00:07.001 Recognize this gentleman. In English, she is called cockroach, croton bug, 00:00:07.001 --> 00:00:09.001 roach, water bug, or black beetle. 00:00:10.000 --> 00:00:13.000 The Germans call him Shabin, the French Leblat, and in 00:00:13.000 --> 00:00:15.000 Spanish, she is known as La Cucaracha. 00:00:16.000 --> 00:00:19.001 No matter what the language or country, the cockroach is an unwelcome and 00:00:19.001 --> 00:00:21.001 disgusting pest in any home. 00:00:22.000 --> 00:00:26.000 Let's take a look at SeƱor Cucaracha, how and where he lives, and better 00:00:26.000 --> 00:00:28.000 still, how to get rid of him. 00:00:43.000 --> 00:00:47.001 Roaches are one of the oldest insects, having lived in the days of the dinosaur. 00:00:48.001 --> 00:00:51.001 Fortunately for us, the size of our roach today is extremely 00:00:51.001 --> 00:00:54.000 small compared with his ancestor. 00:00:54.000 --> 00:00:58.000 Roaches of the days of the dinosaur were several feet long. 00:00:58.001 --> 00:01:02.001 Today, some roaches found in the tropics grow three or four times larger 00:01:02.001 --> 00:01:04.000 than our common American cockroach. 00:01:06.000 --> 00:01:09.000 The true home of the roach is outdoors, beneath the bark 00:01:09.000 --> 00:01:10.001 of trees and under rocks. 00:01:12.000 --> 00:01:16.001 This has resulted in their bodies, heads, and legs becoming flattened, allowing 00:01:16.001 --> 00:01:19.000 them to hide in small cracks and crevices. 00:01:21.001 --> 00:01:26.000 There are about 2,000 different kinds of roaches, but only four have 00:01:26.000 --> 00:01:28.000 adapted to life indoors. 00:01:28.001 --> 00:01:30.001 The largest of these is the American roach. 00:01:31.000 --> 00:01:34.001 Adults may be from one and a half to two inches long, reddish 00:01:34.001 --> 00:01:36.001 brown to dark brown in color. 00:01:39.000 --> 00:01:45.000 The Oriental cockroach, sometimes called black beetle because of their short 00:01:45.000 --> 00:01:47.001 wings, heavy body, and dark color, are slightly 00:01:47.001 --> 00:01:49.001 smaller than their American cousin. 00:01:52.001 --> 00:01:57.001 The brown banded roach is the smallest of our four kinds and brightest in color. 00:01:58.001 --> 00:02:02.000 They like high places, such as the ceiling and upper cabinets in a kitchen. 00:02:02.001 --> 00:02:04.000 This makes them a little harder to control. 00:02:05.000 --> 00:02:09.000 The German roach is the most common and is often called croton bug or water bug. 00:02:10.000 --> 00:02:13.001 Adults are slightly larger than the brown banded, but are still less than one 00:02:13.001 --> 00:02:15.000 inch long and light brown in color. 00:02:18.000 --> 00:02:23.000 Here are all four together, left to right, the American, Oriental, 00:02:24.000 --> 00:02:25.001 brown banded, and the German. 00:02:31.000 --> 00:02:33.001 Roaches may come into a home several different ways. 00:02:34.001 --> 00:02:37.000 Sewers or basement drains are one of the most common. 00:02:39.000 --> 00:02:43.001 They can also enter through any openings in the walls, such as around electrical 00:02:43.001 --> 00:02:49.001 conduits or plumbing, or through cracks in the baseboard or under doors. 00:02:52.000 --> 00:02:56.000 Roaches can be carried into a home in laundry packages or in boxes of groceries. 00:02:56.001 --> 00:03:00.001 All packages which might possibly contain roaches should be examined carefully. 00:03:01.001 --> 00:03:05.001 If an adult carrying an egg capsule gets away, a population 00:03:05.001 --> 00:03:07.001 of roaches is likely to develop. 00:03:08.001 --> 00:03:12.000 The capsule which may contain as many as 48 eggs is 00:03:12.000 --> 00:03:14.000 deposited in a hidden location. 00:03:15.000 --> 00:03:19.000 When the eggs develop into young roaches, they push open the capsule to emerge. 00:04:10.001 --> 00:04:13.001 These young nymphs are extremely active and will begin 00:04:13.001 --> 00:04:15.001 to search for food immediately. 00:04:17.001 --> 00:04:21.001 A few days later, the young roaches turn to a yellowish brown color. 00:04:24.001 --> 00:04:28.000 Still in the nymph stage, these roaches are almost grown 00:04:28.000 --> 00:04:29.001 but have not yet developed wings. 00:04:31.001 --> 00:04:33.001 Wings are present only on adults. 00:04:39.000 --> 00:04:43.000 After several generations, a large colony will develop, creating a very 00:04:43.000 --> 00:04:45.000 unpleasant odor in the house. 00:04:46.001 --> 00:04:50.001 Roaches destroy food, damaged fabrics, books, and other materials. 00:04:50.001 --> 00:04:56.000 By polluting food over which they run, they spread filth and may carry diseases. 00:04:59.001 --> 00:05:05.000 When roach populations build up, their presence is easily noted by roach spots in 00:05:05.000 --> 00:05:09.001 places where they congregate, such as in cabinets, drawers, and behind pictures. 00:05:12.000 --> 00:05:15.000 Roaches hide during the day in sheltered dark places. 00:05:15.001 --> 00:05:18.000 At night, they come out in search of food and water. 00:05:20.001 --> 00:05:25.000 A good way to find roaches is to enter a dark room quietly, snap on the lights, 00:05:25.001 --> 00:05:28.001 and watch where they run to hide. 00:05:31.001 --> 00:05:35.001 They may be found in cracks in the baseboard, around 00:05:35.001 --> 00:05:37.001 water pipes underneath the sink, 00:05:40.001 --> 00:05:44.000 behind cabinets, or any other place they can hide from the light. 00:05:45.001 --> 00:05:50.001 Scientists have worked for years developing insecticides to control roaches. 00:05:51.001 --> 00:05:56.000 DDT proved fairly effective, but later another chemical, chlordane, was 00:05:56.000 --> 00:05:59.001 developed, and today it is considered to be one of the most effective 00:05:59.001 --> 00:06:01.001 insecticides for roach control. 00:06:02.001 --> 00:06:05.001 Chlordane is available in liquid or powder form. 00:06:06.000 --> 00:06:11.001 For home use, it should be purchased as a 2 to 3 percent oil base spray or as a 00:06:11.001 --> 00:06:13.000 5 to 6 percent dust. 00:06:14.000 --> 00:06:18.001 Read the label of any insecticide you purchase to make sure it contains the 00:06:18.001 --> 00:06:20.001 proper amount of the active chemical. 00:06:23.000 --> 00:06:30.000 A single treatment of chlordane applied correctly leaves an 00:06:30.000 --> 00:06:33.000 invisible film which gives protection for several weeks. 00:06:34.000 --> 00:06:38.000 For most effective results, the material should be applied to all secluded places 00:06:38.000 --> 00:06:42.001 and cracks so that no matter where the roach tries to hide, he will come 00:06:42.001 --> 00:06:44.000 in contact with the residue. 00:06:45.000 --> 00:06:47.000 Special attention should be given to baseboards. 00:06:50.000 --> 00:06:53.001 The area under the sink should be treated carefully, as it is a 00:06:53.001 --> 00:06:55.001 favorite hiding spot for roaches. 00:06:59.000 --> 00:07:04.001 Especially around the water pipes where roaches often enter. 00:07:08.000 --> 00:07:12.001 Hard to reach places such as behind the stove can be effectively treated 00:07:12.001 --> 00:07:14.001 with the dust form of chlordane. 00:07:15.000 --> 00:07:17.001 A small puff duster makes the job easier. 00:07:20.001 --> 00:07:25.000 If cabinet drawers are cleaned thoroughly, it will not be necessary 00:07:25.000 --> 00:07:26.001 to treat inside them. 00:07:27.000 --> 00:07:31.000 A small paintbrush makes it easy to apply the insecticide around the 00:07:31.000 --> 00:07:32.001 back and under surfaces. 00:07:39.000 --> 00:07:43.001 Before treating cabinets and other storage places, first remove 00:07:43.001 --> 00:07:45.000 all food and utensils. 00:07:45.001 --> 00:07:50.000 Here again, the brush makes it easy to apply the insecticide effectively. 00:08:04.001 --> 00:08:08.001 After the insecticide dries, the shelf should be covered with paper before 00:08:08.001 --> 00:08:10.001 replacing the food or utensils. 00:08:14.000 --> 00:08:18.000 Proper and thorough treatment will eliminate Mr. Roach from this 00:08:18.000 --> 00:08:19.001 kitchen for some time to come. 00:08:20.000 --> 00:08:23.001 Treatment of other areas of the house where roaches are found will aid in 00:08:23.001 --> 00:08:25.001 making a roach-free home. 00:08:30.001 --> 00:08:34.001 Roach-free communities are the result of careful planning and cooperation of 00:08:34.001 --> 00:08:37.000 city, county, and state organizations. 00:08:39.000 --> 00:08:42.001 Citywide campaigns are successful in eliminating roaches 00:08:42.001 --> 00:08:44.001 where they breed in large numbers. 00:08:46.000 --> 00:08:50.001 The application of chlordane dust to sewers in other breeding places has become a 00:08:50.001 --> 00:08:52.001 standard practice in many cities. 00:08:53.000 --> 00:08:56.001 This is often done with the cooperation of commercial exterminators. 00:09:00.001 --> 00:09:06.001 With both individual and community action, we can control roaches in our homes 00:09:06.001 --> 00:09:09.001 and reduce the nuisance and danger of this common pest. 00:09:10.001 --> 00:09:15.000 The development of insecticides has kept pace with our modern way of life. 00:09:15.001 --> 00:09:18.001 Today, chemicals are available which will kill insects 00:09:18.001 --> 00:09:20.000 weeks after they're applied. 00:09:20.000 --> 00:09:25.001 Through proper use of these chemicals by individuals and communities, we can say 00:09:25.001 --> 00:09:30.001 goodbye to Mr. Roach, our number one household pest. 00:09:50.000 --> 00:10:09.001 [...]
